This 7" x 1/2" A36 Hot Rolled Steel Flat Bar is a versatile structural steel ideal for heavy fabrication. Conforming to ASTM A36 with a minimum yield strength of 36,000 PSI, it offers excellent weldability and formability for frames, supports, and base plates. In stock Los Angeles.
- A36 Steel Construction
- ASTM A36 Certified
- 58,000-80,000 PSI Tensile Strength
- Excellent Weldability and Formability
Hot Rolled A36 Steel Flat Bar is formed at elevated temperatures, resulting in a product with a distinctive scaly, blue-grey finish and slightly rounded edges. This cost-effective process produces a material with good overall mechanical properties and excellent weldability using common methods. It conforms to ASTM A36 specifications, ensuring a minimum yield strength of 36,000 PSI for reliable performance in structural roles.
As a large-profile bar, this 7-inch wide steel is ideal for applications requiring significant load-bearing capacity and a wide footprint. It serves as robust base plates for columns and machinery, heavy-duty structural braces, and key components in industrial equipment frames where strength is paramount.

Finish Options
This product comes standard with a hot rolled mill finish, characterized by a blue-grey color and a surface scale. This scale must be removed by grinding, sandblasting, or pickling before painting, powder coating, or galvanizing. Left unfinished, the steel will rust. Contact our Los Angeles sales team for custom finish inquiries.
How to Measure
Flat bar is measured by its Width (the larger dimension of the flat cross-section) and its Thickness (the smaller dimension).
Example: To order this flat bar, specify "A36 Hot Rolled Flat Bar, 7 inches wide by 1/2 inch thick".
